ANY of these DEVICES EXCEPT Marshmallows. IF YOU LAUNCH
anything else with these catapults you could injure your eye
or someone else's eye or other parts of someone's body. If you
do launch marshmallows be certain they are the large ones not the
small ones because a small one could get stuck in a child's throat.

Simple one to build

Scouts and Schools enjoy a game I
teach called catapult. I bring a catapult with
me. Marshmallows are hurled at a target,
sometimes the target is me, and we determine who
would have made the best catapultists. However,
some groups make their own catapults before I
come and they determine who has made the best
catapult by firing marshmallows at each other's open mouths.
